Ecshop in the init.php file

Ecshop in the init.php file

Under the includes/init.php directory

For work reasons, need to ecshop two times development, by the way to record some of the Ecshop source code analysis:

The first is the init.php file, which is called on every page of Ecshop, and is used to analyze it first:

Usage: int ob_get_length (void) Description: This function returns the length in the current buffer, as in ob_get_contents if the output buffer is not active. FALSE is returned. 5.

The above describes the Ecshop in the init.php file in detail, including the contents of the ecshop,init.php file, I hope that the PHP tutorial interested in a friend helpful.
